A study on high speed control of step motor using current source

전류원을 이용한 스텝 모타의 고속 제어에 관한 연구

In this study, a method of obtaining reasonably large and constant torque at high speed is given in order to improve the performance of the open loop controlled step motor system using the current source, thus resulting in high performance compared to the conventional current limiting using resistor and chopper.
